Lithium battery aluminum foil performance advantages

Aluminum foil is a hot stamping material which is directly calendered into a thin sheet of metal aluminum. Its hot stamping effect is similar to that of pure silver foil stamping, so it is also called fake silver foil.
Aluminum foil is the key material in the positive electrode of lithium battery. According to CNKI data of China Knowledge Network, the amount of aluminum foil for 1GWh lithium battery is about 600-800 tons.
Advantages of battery aluminum foil in lithium battery application: inhibit battery polarization, reduce thermal effect, improve rate performance; reduce battery internal resistance, and significantly reduce the dynamic internal resistance increase of the cycle; improve consistency, increase battery cycle life; The adhesion of the active material to the current collector reduces the manufacturing cost of the pole piece; protects the current collector from corrosion by the electrolyte; and improves the processing property of the lithium iron phosphate and lithium titanate materials.
Performance advantages of : significantly improve the consistency of battery pack use, greatly reduce the battery composition; improve the adhesive adhesion of active materials and current collectors, soft materials, easy processing, reduce the cost of manufacturing pole pieces; reduce polarization, improve Magnification and gram capacity to improve battery performance; protect current collectors and extend battery life.
